QA1 78-88 GM G-Body/82-02 Chevrolet Camaro Lower Boxed Trailing Arms

Lower box-style trailing arms for 78-88 GM A-bodies and G-bodies. Made with .12" wall thickness and have greasable bushings. All upper tubular and lower boxed trailing arms use polyurethane bushings on both ends, while upper adjustable and lower tubular trailing arms use a spherical ball or rod end assembly on the chassis end to eliminate bushing bind, allowing the suspension to move smoother for better control. This keeps the tires planted firmly on the ground for improved traction and a more predictable, better handling car. For a long-lasting finish, tubular and boxed trailing arms are powder-coated gloss black, while the adjustable arms are zinc plated and anodized. Boxed Trailing Arms are constructed from 0.120'' wall cold rolled steel tubing for maximum strength and flex elimination. These trailing arms have fluted, greasable polyurethane bushings, which are superior to the stock rubber bushings. Tubular Trailing Arms are constructed from 1-1/4'' diameter, 0.120'' wall steel tubing which offers increased strength over other designs, but also have the added advantage of lighter weight. These trailing arms have fluted, greasable polyurethane bushings, which are superior to the stock rubber bushings. Heavy-Duty Adjustable Trailing Arms allow easy rear suspension adjustments for optimum handling and traction. Simply loosen the jam nuts and adjust the pinion angle without removing the arms from the vehicle. They replace soft OE differential bushings with polyurethane differential bushings, and they use a spherical ball or rod end assembly with UHMW polyethylene bushings on the chassis end to allow the rear suspension to move more freely and eliminate bushing bind. All parts sold in pairs.

• Adjustable arms offer easy wheelbase and pinion angle adjustment
• Direct fit options for many popular GM, Ford & Mopars
• Easy, bolt-in install
• Made in the USA

Upgrade the rear suspension of your GM A-body or G-body with QA1 QAP5204 lower boxed trailing arms. Designed as a direct-fit, bolt-in replacement for the original equipment arms, these components improve rear suspension control, traction, and handling without requiring extensive modifications. The boxed design is manufactured from cold-rolled steel tubing with a .120-inch wall for increased strength and reduced flex compared with factory-style components.
The QA1 QAP5204 trailing arms feature fluted, greasable polyurethane bushings that provide greater durability and control than standard rubber bushings. Greasing the bushings helps maintain smooth suspension movement, while the firmer polyurethane construction helps keep the rear tires planted during acceleration, cornering, and other demanding driving conditions. The bushings are installed at both ends for a secure, performance-oriented connection between the chassis and rear axle.
Finished in durable gloss black powder coating, these lower boxed trailing arms resist corrosion and provide a clean appearance beneath the vehicle. The arms are sold as a pair and are engineered for straightforward installation using the factory mounting locations. QA1 manufactures these trailing arms in the USA, providing a reliable suspension upgrade for street-driven, performance, and restoration applications. Fitment includes select 1978-1988 GM A-body and G-body applications, including the Pontiac LeMans and Grand Prix listed for this part.
